The tape. The sensor.
The patented sensor system is integrated directly into the band. This means the band measures your performance during your workout, no matter where you pull.
The band simply connects to your smartphone via Bluetooth. You can easily charge your band via USB-C and train for up to 24 hours on one charge.
Stick to your fitness routine and work out anywhere, anytime. The only thing you need is your band and the app.
STRAFFR training is for both beginners and advanced. Choose the band that suits you - either Medium with 5-15 kg or Strong with 15-25kg.
